How to let people see message in add-on preference?
Type your text in add-on preference script:
bl_info = {
    &quot;name&quot;: &quot;Example add-on&quot;,
    &quot;author&quot;: &quot;Your name here&quot;,
    &quot;version&quot;: (1, 0),
    &quot;blender&quot;: (2, 92, 0),
    &quot;location&quot;: &quot;Your location here&quot;,
    &quot;description&quot;: &quot;Your description here&quot;,
    &quot;wiki_url&quot;: &quot;&quot;,
    &quot;tracker_url&quot;: &quot;&quot;,
    &quot;category&quot;: &quot;Development&quot;,
}


import bpy

class AddonPreferences(bpy.types.AddonPreferences):
    bl_idname = __name__
    def draw(self, context):
        layout = self.layout
        col = layout.column()
        #Type your text
        self.layout.label(text=&quot;Your text here&quot;)

def register():
    bpy.utils.register_class(AddonPreferences)

def unregister():
    bpy.utils.unregister_class(AddonPreferences)
